ABSTRACT:
The present invention relates generally to substantially liquid, chlorine-free, sulfur-bridged phenols useful as antioxidants and more specifically to the preparation of a substantially liquid, chlorine-free, sulfur-bridged, hindered phenol compositions which are effective antioxidant(s) in lubricating oils without causing excessive copper corrosion. The invention also includes lubricating oils containing an antioxidant additive of the present invention, as well as a method of reducing oxidation in the lubricating oil used in a machine such as an internal combustion engine.
